Biggerplate.com is a repository of mind map program files (that is, the setups that actually produce the mind maps). The downloads are free and can be helpful for learning mind mapping.
I make a selected (and expanding) set of my mind map files available on Biggerplate. Click the image to go to the Biggerplate site and a list of my available maps.
Note. You must have the iMindMap program to use these files.
